Java BeanCurrentlyIncremationException春季启动

如何修复此异常

没有弹簧靴，一切正常

问题出在“应用”部分，对吗

抓住例外

BeanCurrentlyInCreationException: Error creating bean with name 'pooledConnectionFactory': 
Requested bean is currently in creation: Is there an unresolvable circular reference?

应用程序

通过导入使用Bean

<import resource="classpath*:contexts/database/datasource/base-data-source.xml"/>
<import resource="classpath*:contexts/database/datasource/pooled-data-source.xml"/>

导入的第一个文件：

Spring Boot具有与数据源配置冲突的功能。请参见

DataSourceInitializer

class。它尝试在创建数据源之前获取数据源。

要修复你的应用程序，你可以

使用属性禁用初始值设定项

spring.datasource.initialize=false

排除数据源自动配置，因为您有自己的配置

@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})

在Spring Boot中使用Hibernate和HSQL还需要什么？也许是测试用的？public void beforeTestClass（TestContext TestContext）引发异常{IDatabaseConnection databaseDataSourceConnection=new databaseDataSourceConnection（（DataSource）TestContext.getApplicationContext（）.getBean（“DataSource”）；databaseDataSourceConnection.getConnection（）.prepareStatement（“将数据库引用完整性设置为FALSE”）.execute（）；}
